If you’re designing a website and you’re stuck for ideas, try StrangeBanana. It randomly generates a page layout complete with menu bar, which you can copy and use for free. Every time you refresh the page, a new design is created which has never been seen before.
It’s fun to play with, but some of the designs aren’t that nice to look at, and they’re all really just variations on a theme. I probably wouldn’t copy a StrangeBanana design verbatim, but I’d use the site as a tool for inspiring my own designs.
